How to Play ARF file on Ubuntu 10.04-10.10-Linux

Play ARF file by Converting them to mp4



ARF i.e Advanced Recording Format is a format recorded by NBR(Network Based Recording).For Ubuntu or other Linux versions currently no player is available which can play .arf files i.e WebEx(Player used to play and convert arf and wrf formats) is not supported on Linux based system or Ubuntu 10.04.That’s why to play arf file only one option is available and that is to convert the arf format to mp4 or swf or other simple formats.So you can use a converter tool “NBR2MP4″ to generate mp4(That we can play Using VLC player) file from arf.



Playing ARF format by converting them to mp4 : Ubuntu 10.04 ,Linux based systems

NBR2MP4 is a simple tool and converter that can be used to convert arf formats to mp4 formats.You can install it from command line in few steps(It’s very simple).



Download arf converter for Ubuntu 10.04 and other Linux distros

download nbr2mp4 for ubuntu





Install ARF converter on Ubuntu 10.04 or on linux


1. After downloading the nbr2mp4.tar file,extract it to any directory e.g extra_softwares.It will create a directory nbr2_mp4 and a script file nbr2mp4.sh.
2. Then Make the file nbr2mp4.sh executable by typing this command on the terminal-

rkjha@rkjha-desktop:~/extra_softwares$ chmod +x ./nbr2mp4.sh


3. Next,Install the converter by typing the command-

rkjha@rkjha-desktop:~/extra_softwares$ ./nbr2mp4.sh



Type the directory where you want to install the software[/home/rkjha/extra_softwares]:
Extracting files…
Installation is complete.



When it will ask “Type the directory where you want to install….” then just hit enter to install in the current directory(extra_softwares).


4. That’s All…You have installed the arf to mp4 converter successfully..
Converting ARF format to MP4: Ubuntu-Linux


Now,first go to the directory nbr_2mp4 created in extra_softwares(The Directory where you installed the nbr2mp4).next,use the following command to convert format-

./nbr2mp4 SOURCE [MP4-DIRECTORY] [FPS]


Where SOURCE means the name of the arf file which you want to convert and don’t forget to specify pathname if it is in the different directory.MP4-DIRECTORY stands for the output file i.e filename.mp4,it’s name will be same as arf file except the extension of .mp4(Use ./ to generate in the same directory as of input file).In FPS(Frame Per Second) field you can specify between 3 to 10(Default value is 5).The quality of the mp4 file(output file) is directly proportional to the FPS.
e.g



rkjha@rkjha-desktop:~/extra_softwares/nbr2_mp4$ ./nbr2mp4 tutorial1.arf ./ 8
Converting /home/rkjha/extra_softwares/nbr2_mp4/tutorial1.arf to /home/rkjha/extra_softwares/nbr2_mp4/./tutorial1.mp4
Retrieving video data, fps=8…

How to Increase the speed of Firefox Browser

Mozilla Firefox is one of the most popular browser on the Internet.It is open source and Free.It is available for all operating systems like Linux based(Ubuntu 10.04),windows,MacOSX …So This post will try to explain about a trick you can use on Firefox browser to increase the page loading speed.The trick is based on the concept of HTTP Pipelining.


What is HTTP Pipelining?

(Those users who just want to know about trick may skip this part)
HTTP(Hypertext Transfer Protocol) Pipelining is a simple technique by using that more than one HTTP requests are send to a single socket.It is supported in HTTP/1.1(IT isn’t supported in HTTP/1.0).It all happens due to the fact that ,several HTTP request can be fitted in the same TCP(Transmission Control Protocol) packet so the total number of TCP packets sent on the Internet is reduced and thus result in less load on network.


Why Browsing Speed Increases?

Without HTTP Pipelining ,HTTP requests are sent out in successive order i.e one after another but If we use HTTP Pipelining then the request can be sent to the server more quickly that’s why the page loading time will decrease.Therefore the browsing speed will increase and surfing become faster with Firefox browser.


Speed Up Mozilla Firefox Browser

To utilize HTTP Pipelining,what you have to do is to just enable the HTTP pipelining in Firefox because it is disabled by default in Firefox version 3(or in greater version,It may not be supported in older versions,if so then first upgrade your browser).

Step1 : Open Firefox Browser and Type about:config in Address Bar and hit enter.

step2 : Now type network.http.pipelining in Filter box

Before Changing the Settings(Firefox Browser),it was like this -

how_increase_the_speed_of_firefox_browser.png



step3 : Change the value field of network.http.pipelining,from False to True(By Double Clicking on it).

Step4 : change the value field of network.http.pipelining.maxrequests from 4 to 8(or more).

step5 : You may like to change or not in third field,actually it is for servers that uses SSL.If you want then change it to true leave it untouched.

After Changing the Settings(Firefox Browser) , Now looks like -

Step6 : That’s All..You are Done!! Enjoy Surfing Faster on Firefox Browser..
